ABSTRACT:
A remote satellite modem, in conjunction with a mediation device configuration propagates frames over a cellular backhaul link so as to preserve PRC traceability by receiving a frame based signal, in which the frame based signal conforms to a hub timing signal operable to demarcate frames in the frame based signal, and identifies a start of frame in the received frame based signal, such that the start of frame is independent of the symbol timing of the hub timing signal. In response to the start of frame, the modem generates a timing packet corresponding to a remote timing signal, and forwards the timing packet and the frame based signal, in which the timing packet is for decoding the frame based signal corresponding to the hub timing signal using the remote timing signal.
